16 Claims.

My invention relates to apparatus and means for applying rail bonds to rails and particularly to that type of bond in which the terminal is expanded within an opening or oriflce through some portion of the rail.

One object of my invention is to provide a means for installing what may be termed a pinexpanded bond by forcing a pin into a solid bond terminal thus expanding the terminal into intirnate contact with the surface of the rail.

Another object is to provide means for forcing the pin into the solid terminal through the medium of a force created by the expansion of gases as in the case of gun powder, dynamite, etc.

Further objects will be revealed by the disclosure in the specification and drawings. I

In applying bonds of the expanded type, such expansion has been brought about by applying a force to the opposite faces of the bond terminal 3 thus tending to shorten the bond thereby increasing the diameter and forcing the terminal into contact with the surface of the rail.

Other types of bonds, known as the pin-driven or pin-expanded type, have depended upon the forcing of a pin into an orifice extending through the terminal of the bond and which was of smaller diameter than the pin, but this has not been entirely satisfactory because if the pin was not forced into the terminal in axial alignment with the orifice, then the full expansion of the terminal was not secured.

In the latter case the pin has usually been forced into the terminal by means of hammer blows applied to the end of the pin, but in my improved method I force a steel pin into a solid terminal through the medium of forces set up by the explosion of gun powder or other explosive.

I have also provided a unique toolor apparatus for applying the bond as pointed out above, and this tool provides quick application and removal, and also provides a high degree of safety against premature firing of the explosive.

In the drawings:-

Fig. 1 is a side view in partial section of my invention shown in position on a. rail for application of the bond terminal.

Fig. 2 is a top view of Fig. 1.

Fig. 3 is an end view of the breech block shown in Fig. 1.

Fig. 4 is a section of Fig. 3 taken on the lines Fig. 5 is a View in partial section of the priming mechanism.

Fig. 6 is an enlarged sectional view of the barrel shown in Fig. 1.

Fig. 7 is a view: in partial section of the firing portion of my invention and differs from the cor-' responding parts shown in Fig. 1 in that the barrel is in safety position while in Fig. 1 the corresponding parts are in position for firing.

In the preferred embodiment of my invention I provide a frame F provided with legs I and 2 held in pivotal relation by the transverse hinge pin 3.

The member I is provided with side projecting lugs 4 in which are threadedly mounted adjusting screws 5 by means of which the position of the tool with respect to the bond terminal may be changed to meet varying conditions. The screws 5 are a. convenience in positioning the tool upon the rail as they act as a support for the tool until it is clamped in position.

The upper ends of the members I and 2 are provided with toggle levers 6 and 1 of which there are two of the latter. The lever B is pivotally secured to the member 2 by means of the hinge pin 8 and is positioned between the spaced lugs 9. The lever 6 is provided with integrally formed operating handle Ill.

The toggle levers I are pivotally secured to the member I by meansof the hinge pin II and are positioned on opposite sides of the projecting lug l2.

The toggle levers 6 and 1 are pivotally secured together by means of the hinge pin l3. By means of the toggle arrangement just described it is possible to very quickly move the lower end of the members I and 2 in order to apply or remove the tool from its position on the rail. It is further possible to secure by proper adjustment of the parts a very powerful grip of the tool upon the terminal and rail and the proper adjustment is easily secured by means of the adjusting screw M which is threadably mounted at the lower end of the member 2 and is provided with a projection l5 by means of which the screw is rotated and provided with a lock nut I6. The end face I! of the screw I4 is adapted to engage the head l8 of the bond terminal.

The lower end of the member I has a, passage therethru of two portions, the portion l9 being 24 an opening 25 extends in which is positioned a portion of the priming pin.

The priming mechanism consists of a cupshaped member 26 having a bore 21 in which is mounted the priming pin 28. 'The pin has a projecting portion 29 which extends into and through thepassage 25 in the breech block. The pin is normally held in its retracted position by means of the spring 30 which is positioned between the head 3| of the pin and the face 32 of the breech block.

The closed end of the member 26 has its exterior formed as the frustrum of a cone with the sloping surface 33 and the flat end surface 34. The face 34 is adapted to bear against the end face of the screw 35 which limits the longitudinal movement of the member 26 under tension of the spring 30. The face 33 of the member 26 is arranged to be engaged by the operating pin 36 which is slidably positioned in the opening 31 and has a face 36 corresponding to the face 33 of the member 26.

'- When the upper end of the pin 36 is struck as by means of a hammer and is forced downwardly the faces 33 and 36 co-act to force the members 26 and 23 forward thus forcing the portion 29 of the priming pin against the priming cup of the loaded cartridge 39.

The barrel 2| has a thru-passage 40 slightly enlarged at one end to receive the cartridge 39. The terminal end of the barrel 2| has a counterbore 4| which permits the shank 42 of the bond terminal to project therein. I

The barrel 2| has one or more longitudinal grooves 43 which permit the escape of air as the barrel is moved manually inwardly or outwardly with respect to the breech 22 as the fit between the member 2| and the walls of the passage I9 is very close.

The member 2| is also provided with an annular groove 44 whichis engaged by a spring-heldrball detent 45 when the member 2| has been moved to the position shown in Fig. 7 before the tool is ap-' plied to the rail. When the tool is in position on the rail the member 2| takes the position shown in- Fig. 1 in which the adjacent faces of the members 2| and 22 are in contact or very close. The

detent 45 prevents the member 2| from accidentally shifting its position before the tool is applied to the rail.

The breech block 22 is provided with a plurality of safety pins 46, one of which is shown in Fig. 7 and is mounted in the two-chambered thru-passage 41 and is strongly held in the advanced position by means of the spring 48. In the advanced position the end 49 of the safety pin projects be- .yond the inner face 50 of the breech such that ficient to make it very diflicult to manually move the barrel 2| beyond the locking position shown in Fig. '1, but when the tool is positioned upon a rail and the toggles are operated to force the lower ends of the members and 2 toward each other, the pressure of the springs 48 is very easily overcome and the member 2| is forced to the position aouaaaa shown in Fig. 1. It is now possible by forcing the pin 36 inwardly to explode the cartridge 39.

The cartridge 39 may be said to be an ordinary cartridge having a solid hardened steel projectile 53 and the cup is preferably filled with a smokeless powder pr other high explosive. I prefer to use smokeless powder as it does not affect the bore 46 of the barrel 2|.

When the cartridge has been exploded the projectile 53 is driven forward with great force and speed and it is found that the cartridge will be forced into the solid bond terminal and expand the same in contact with the rail. J

I prefer to make the length of the projectile 53 such that when it has reached its final position in the bond terminal it will take the position 53 in which one end of the projectile extends outside the bond terminal and for a predetermined distance into the bore 40 of the barrel 2|. This arrangement I find eliminates to a very large degree the noise from the exploding cartridge.

The end face of the member I! acts as a stop for the projectile should it for some reason have a tendency to move entirely through the terminal, but I find that this is a very remote possibility for the reason that smokeless powder in the present state of the art runs very uniform as to its explosive power and by uniformly gauging the amount of powder in each cartridge and shaping the projectile to harmonize with same that the penetration of the projectile into the bond terminal is very uniform.

If desired the projectile 53 may be separate from the cartridge 39 in which case the cartridge may be said to be a blank cartridge. I find that under such arrangement the projectile 53 if detached from the shell will penetrate the terminal equally as well as when formed as a part of the shell.

The tool having been properly placed and the cartridge exploded, the tool is then removed and the barrel 2| removed by hand from its holder. The exploded shell will be found mounted in the barrel 2| and is very easily removed and replaced with an unfired cartridge and then the barrel replaced in position.

The tool is very light compared with screw or hydraulic compressors now in use and the penetration which results in the expansion of the terminal is exceedingly uniform and is not dependent upon the workmen.

It will be obvious that after the toggle devices 6 and 1 have been operated to their extended position that further pressure may be applied to the rail and bond head by operating the screw i4; also the barrel 2| may be moved in the bore l9 by means of the screw |4 against the pressure of the springs 48. If of proper length the screw |4 may be used exclusively for applying the device to the rail.

There are other uses to which my invention may be put than that of applying bonds, as for instance expanding rivets in metal plates.

I prefer to have the projectile enter the shank 42 rather than have it enter the head Hi.

There will be many modifications which will suggest themselves both as to the method of bonding being disclosed and the tool therefor, therefore, I wish to be limited only by my claims.
